MQTT working but Belchertown skin 'Failed connecting to weather station'

[Matt]

Hi,

I followed the instructions in https://github.com/poblabs/weewx-belchertown to install an MQTT broker and subscribe to the weather data.  It's working according to the logs...

Weewx syslog

weewx.conf

    [[MQTT]]

        server_url = mqtt://pi:xxxxxxx@localhost:1883

        topic = weather

        unit_system = METRIC

        binding = archive, loop

        aggregation = aggregate

        log_failure = true

        log_success = true

skin.conf

    # MQTT Websockets defaults

    mqtt_websockets_enabled = 1

    mqtt_websockets_host = localhost

    mqtt_websockets_ssl = 0

    mqtt_websockets_topic = weather

    disconnect_live_website_visitor = 1800000

But the webpage constantly says...

I've been over and over the config, re-writing, adding quotes, you name it I've tried it but still no success.  Can any bright spark see something obvious that's wrong...please!!

Many thanks,

Matt

I noticed a typo myself...now changed the websockets port and put the host and topic in quotes, but still not connecting...

    # MQTT Websockets defaults

   mqtt_websockets_enabled = 1

   mqtt_websockets_host = "localhost"

   mqtt_websockets_port = 9001

   mqtt_websockets_ssl = 0

   mqtt_websockets_topic = "weather"

   disconnect_live_website_visitor = 1800000

Your host needs to be the IP of your broker. Not localhost. 

[Matt]

Thank you, that's progress. Now it says 'Connected. Waiting for data' but doesn't change. Again, the logs look ok (to a novice).

Try changing mqtt_websockets_topic to weather/loop

[Matt]

Superb! That worked. Thank you very much.  I am in the UK and use degrees Celcius and Miles per hour.  What should I set unit_system to (METRIC gives me celcius but kmh, US gives me fahrenheit and miles per hour)?

A lot of these items are covered in the documentation. Check out this section. 

[Pat]

Ah, sorry, my mistake. I mis-read your question. 

You'll want to configure the MQTT extension to send the units you want. So you'd want something like shown in this question.

[[MQTT]]
        ... your other mqtt config options here ...
        [[[inputs]]]
                [[[[windSpeed]]]]
                        name = windSpeed_mph
                        units = mile_per_hour

The mqtt extension documentation has more info too.

[Matt]

Yes, I realise that, but my weewx.conf is the same as the section you highlight but I'm still not seeing celcius and mph...

This is my current weewx.conf

    [[Defaults]]

       

       [[[Units]]]

           

           # The following section sets what unit to use for each unit group.

           # NB: The unit is always in the singular. I.e., 'mile_per_hour',

           # NOT 'miles_per_hour'

           [[[[Groups]]]]

               

               group_altitude = foot    # Options are 'foot' or 'meter'

               group_degree_day = degree_C_day    # Options are 'degree_F_day' or 'degree_C_day'

               group_pressure = mbar    # Options are 'inHg', 'mmHg', 'mbar', or 'hPa'

               group_rain = mm    # Options are 'inch', 'cm', or 'mm'

               group_rainrate = mm_per_hour    # Options are 'inch_per_hour', 'cm_per_hour', or 'mm_per_hour'

               group_speed = mile_per_hour    # Options are 'mile_per_hour', 'km_per_hour', 'knot', or 'meter_per_second'

               group_speed2 = mile_per_hour2    # Options are 'mile_per_hour2', 'km_per_hour2', 'knot2', or 'meter_per_second2'

               group_temperature = degree_C    # Options are 'degree_F' or 'degree_C'

Check my previous email. You need to tell mqtt extension what you're looking for. The skin gets its values from mqtt. 

[Matt]

Thank you very much for your help.  I've got it working now...the config I had to add is...

        [[[inputs]]]

               [[[[windSpeed]]]]

                       name = windSpeed_mph

                       units = mile_per_hour

               [[[[windGust]]]]

                       name = windGust_mph

                       units = mile_per_hour
